With 7.4 million users and 240 million saves, Pocket breaks down its most popular content of 2012

Shedding the Read It Later moniker and adapting its save-it-later service to encompass all forms of media back in April, Pocket has been on a tear over the course of 2012.

The service has seen its user base nearly double, rising from 4.5 million users in April to 7.4 million today. Between January and December, items have been saved more then 240 million times, more than four times the amount saved to the service over the previous four years combined.

As we come to the end of 2012, Pocket is doing exactly what a service of its kind should be doing – highlighting the most popular content that its users have saved and shared over the year, creating a slick infographic to illustrate its metrics (embedded below).

Pocket says that its users helped share it wider after it was first published, noting that “80 percent of all ‘opens’ in Pocket happened after the story’s initial four-day rush of popularity—and for every one person who read “Obama’s Way” in Pocket, they introduced the article to an average of 1.4 others outside of Pocket.”

It was followed by the NYT’s Tim Kreider’s piece “The Busy Trap” and the epic hacking story posted by Wired’s Mat Honan, who found his Apple devices wiped and accounts compromised. In fact, three of Honan’s stories are listed in Pocket’s Top 10 articles, possibly making him the most popular writer on Pocket.

What about the most-saved video? Considering it’s about to become the first YouTube video to pass 1 billion views, PSY’s Gangnam Style unsurprisingly tops the charts. According to Pocket, the video remained “within 50% of its peak popularity in Pocket for a whopping 58 days” and didn’t even peak until 70 days after it was first saved to the service.

While most users access Pocket on their computer (28 percent), Apple’s iOS is the most popular mobile platform overall with 37 percent of users using an iPhone (21 percent) or iPad (16 percent). Android follows closely with 35 percent overall, smartphones leading the way with a 25 percent share and tablets with 10 percent.

Demonstrating the rise in sales of connected devices, 75 percent of active Pocket users use two or more apps to connect with the save-it-later service.

With 10.4 items saved to Pocket every second, the service continues to go from strength to strength. It’s been a good year for bookmarking/read-it-later apps and tools and that momentum looks set to carry on into 2013.
